help me .. how to solve this issue

Are you sure you are editing right file? vi /etc/shadow should be vi /a/etc/shadow. When it is asking for password did you try just hitting Enter?

NP means "no password". That should have given you a hint you were not editing the right file ...

yes, i know NP means no passwd .. i just tried removed .. it asking username and passwd .. i cant login to the machine ....

how to solve this issue .. plz help me

Did you try bartus11 suggestions ? (editing the correct file and typing the enter key when prompted for a password)

Code:

 ok boot cdrom -s
# mount /dev/dsk/c1t0d0s0 /a
# TERM=sun; export TERM
# vi /a/etc/shadow

from your file you said you have root as:
root:NP:6445:::::::::
and you removed NP and left:
root::6445:::::::::

Code:

# vi /a/etc/shadow 
remove NP and 6445 they are associated to each other.
Now you should have: 
root:::::::::::

save and exit the file 
# cd /; umount /a
# init 6

And you are done. When it reboots, enter the root login name hit enter.
You will be logged in and then you can change the root password.

Code:

 # passwd root
